T 'o all 'LU/wm it' may conc/ern Beit known that l, Anniv/.o l). N nwooi, a citizen of the United States, residing et Norfolk, in the county of Norfolk, State oi' Virginie, here invented certain new and useful Improvements in Resawmg-Machilies; and l do hereby declare the followingl tovbe e full, clear, and exact description ofthe invention, such :is will enable others skilled in the art to'whicli it apperteins,to make and use the seine.

This invention relates to e re-sewing niachine adapted tol be attached vto and einployed in conjunction with any Well known tye of planer.

n Wood Working mills, et the present time the stock, after it has been dressed by the planer, is vusually rehandled several times before it reaches the re-sewing ineeh'ine, which is generellyloceted in another pertof the building et e considerable dis tance from the planer. This rehendllng of the stock necessarily results in considerable labor, expense and delay. l intend to obvi ateall of this by so constructing my re` sawing machine that it may be erraingedat 1 'and auxiliary 4fto the planer itself, so'tlmt the stock as it passes through! the 4letter is fed directly tothe rc-smving inechnie, thus saying the expense incident to the employ-l ment oi e number oi operators in hend'liii--.

The lat main casting it is only necessary to loosen ter embracesthe bed plate A, upon which the nuts Yand then operate the handle 14 is boltedthe main casting or frame B. The 'so that'the shaft l will be turned or rocked main table of the refsawing machine is and consequently swing or tilt the 'frame e5 shown atC and is. mounted upon the top of D, A nut 23 is employed to hold the tilting 130 1,1 idees 'a Vfra-me on the shaft 4. This tilting frame D forms a support for the saw carrying frames E, one of which is illustrated in detail in Fig. 7. And at this time l might say that Aes the machine is. what might be termed a duplex machine, that 1s to say h'as a pair oi' circular saws, and as. each saw and its connected and operating parts are similar in` adapted to hold the iframe E in sliding engagement With the flanges 18 of the longitudinal bars 17 of the tilting frame. It is intended that the frames E should be shift` ed or moved laterally on the tilting frame D, and to accomplish this l employ the fol lowing mechanisma Formed on the ack of each -frame E are ears 26 having threaded bores 27. A screw shaft 28 is/'provid'ell for shifting each frame E, this screw shaft extending through the threaded bores yot' the ears 26, While the `outer end of each shaft 28 extends throughg'an alining bore in the collar 29, Whichfisl connected with the tiltingI frame D, by the arms 30. Collars 31 hold each shaft 28 against longitudinal movement relative to A the collar 29, so 'that as thc shaft is rotated/the frame E, to which it is -iss applied willflieshifted laterally of the main frame of/t 'if/machine The outer end of each shaftlgzswirnied with a stud 32 for the rec ptirrseb 'VEac frame Ensiidapted to carry one saw and its coperating'part Mln the present machine Ieniploy a 1pair of horizontally7 disposed saws/,gezien of/ Whilchns indicated by the 'lett/er' S duaynf'sauglwill be seen by reference/to Fig. l2, is'. carried .by the reduced stud 33 at the upperI eli/d of the saw arbor 34, and the saw lie' in place by means ofthe stop collanS/,the Washer 36, the nut 37 and the pins 3S, or if desired, any other suitable means may be employed for securn ing the smv to its arbor. 4s/infill be seen by reference to Fig. 7, the'upper portionof the frame E is formed with a half-boxing 8 9 for the reception of the upper portion of the arbor 34, `While the lower portion of the frame E is also formed to constitute a halibqxing 40 for the reception ofthe lower end of the arbor, only in this case the semi-circular, arbor seating section of the boxing is. formed with a series 'of circumferential grooves 41. The lower end of the arbor 34 is keyed to a sleeve 42 sojthat it may slide therein, anl the outer surface of this sleeve 1s formed with circumferential ribs' 43 Which are designed to lie in the grooves 4l of the halfboxing 40. The Whole "boxing for the sleeve 42 is completed by the box section 44, which is likewise semi-cir# cular in form, and has its interior Wall groelyed as at ,45 to match the companion grooves 41. This box4 section 44 is made with an oil cup 46, rom/ which leads an oil port 47- t0 the sleeve 42, the cup having a pivoted closure 48. The bottom ot' this box section 44 forms a portion of the top of the gearbcasing at the bottoni of the machine.. Thaboxing for the upper 'portion of the arbor one-half of Which is formed by the section39, as above stated, iscompleted by' the box section 50, as is shown in Fig. 13.

This box section 50 is also formed with anoil cup 5l, `having a pivoted cover 52 and an oil duct 53 leading through the semi circular Wall of the box section 50.

Between the upper and lower bcxings, the frame E is formed with a relatively large central opening 54 Which provides a suli-A cient space for the central portion oit' the arbor 34 and its appropriate bearings. As will be seen by reference to Fig. l2, the central portion of the arbor is formed with a series of circumferential ribs 55 and the boxing for this part of the arbor is shown in detail in Figs. 9 and 10. Such boxing is made of the semicylindrical section 56 ably rest upon thev shoulders 58 formed at the baseroiz the vertical flanges 59 of the frame E. The semi-cylindrical portion of this boxing section 56 'is provided with grooves 60 for the reception of the ribs 55 of the arbor-. In Fig. 10 is shown the other portion of the central boxing which is com'- posed of a semi-cylindrical section'6l, from which extend the side flanges 62, and bolts 63 passing through the -alining apertures 64 in both boxing sections 56 and 61 connect-` -these sections to form the'complete boxing.

The second section of the boxing shown in Fig. 1 0 is also formed with an oil can '65, from which leads an oil duct 6 6 to "cdnvey the lubricant tothe arborn One ci the flanges 57 of the box section 56 has extending` therefrom an arm 66, the outerendof which is provided with a verticalbored head .formed 'with the side iianges 57 which slidsplit at 68 and terminating in the bored lugs 69 which receive the a ust' screw 70. Boltd to the central'porti'on 1Iione of the ianges' 59 is a plate '71 carrying an angular arm Z2'Whichl3elmimtes ina bored head '78, and this bored head lies beneath and alines withthe-bored head 67 at the end of the arm 66. A hand screw 7,4 is rotatably mounted in' the head-67 and has a threaded shank 75 Which -extends'through'and en# gages the threaded -bore ofthe headflthis" hand screw being operated b y thev hand,

wheel 76.' Thusy it .will be seen that the head 73 the 'arm' forms a hearing -for l the hand screw so that as the latter is rotated the central boxing, made up of `the connected sections 56 and 61, will be raised or lowered and consequently the shaft arbor will be raised or lowered, and this without disturbing' the sleeve 42, for as the arbor is keyed in the sleeve, it may slideftherethrough without aiecting the latter. To the opposite flange 59 of the frame E to which is connected the late 71, I secure a retaining plate 7 7 by bolts or the like.

[From the construction of the arbor and litsVmountings, thus far described, it willibe A seen that vlemploy substantiallyV three box-- o inggwhich 'areyan upper-bondig, an ,inter- Iediate boxing, which also forms a means for raising andy lowering ythe shaft, and a lower boxing "which receives the sleeve 42 tol which is keyed the arbor, so that while the arbor may rotate under the movement received when the' sleeve is turned, as here, iuafterndescribed, the arbor may at the same ,time be adjusted longitudinally of the sleeve without disturbing the latter. It will be note-d that eachof these 'boxings is provided with an oil cup for' a lubricant.. The 'set screw 70, whichv is threaded in Vthe lug (i9 of the split'head 6i is intended to be 0perated to tighten orvloosen the bearing of the screw 73i For the purpose of' driving the'saw arbors 3e and rotatingjthe lcircular saws S, 1 employ the following construction: Located 'at the bottom portion of each vframe D is a oggfear easing78, as best\shovvn in Fig. 5. The

Y lower, portion of the sleeve ,42 extends through the top of thisV 'gear casing and the endpoi'tion ofthe sleeve hasfast thereon a horizontal bevel pinion 79. Within the cas- 105ing and meshing with'this pinion is a bevel gea'iwhefel 80, which is-- fast on. the inner endiojf-th 'sleevel whichvprojects intothe casing.; his sleeveisprovided with a series 'of circumferential' ribs 82.Which turn l1min grooves 83 formed fin' the shaft boxing which-ips composed offtwo sections v84 and S bolte'dtogether. The top section 84' is cast integral or formen partl of the frame llsfhile the lower section 85 of the boxing lysis a .separate semi-cylindrical piece. l Thus iaspulley t0 which may the-'sleeve 8 1. is designed to rotate in its boxingkandj'consequently ,turn the gear wheel 80,`v To-turn the sleeve I provide the power shaiitfto ,which the sleeves 81 are keyed,

ranas at "07, this Jshaft extending loosely through the gear wheels S0. @ne end pori tion of the power shaft SS'is journaled in the beaninS at the end of the arm 89, and

thisend pif-the shaft is rovided with a bell' Y lie belted with any suitable source of power.- lt will thus be noted at while the sleeves may be rotated intheir boxings (they `are -held against longitudipal movementrelative thereto while? the draft maybe adjusted longitudinally of such sleeves, this being desirable when truing up the machine while assembling. lt will thus be noted that when the shaft 86 is rotated motion will be imparted to the arbors 34 and the saws S will he driven.

To properly and accurately direct the stock from the planer to the saws, I provide the verticallydisposed spaced guide strips. 91, the straight parallel sections 92 of which extend upward from the table C of the resaw machine, While the outwardly curved end sections 93 of these guide strips extend beyond the edge of the table and toward the planer-so that they form a flared mouthtor the reception of the stock coming fromthe planer. These guide strips 91 are adapted to be adjusted relatively to each other to accommodate 'pieces of stock of diderent widths, and to accomplish this I provide for each strip an angle bar 94, the. horizontal" side of which is perforated fouthe reception of adjusting bolts 95, which vbolts project through slots 96 in the table C so that the'angle bar may be lshifted and adjusted along the length of the slots, as will be readily understood. rEhe vertical side 97 of each angle bar is provided with bolts 98, the Shanks of which project inward beyond the side 97 and are formed with heads 99. TheLL presser foot is supported from the cross bar 102 by means of its vertical arm 105i`r slotted at 10e for the passage of the adjusting bolt` 105,- Which extends throughd the horizontal .i

slot 106 in the bar 102. This bolt 105 is provided with the usual nut 107 so that it will be seen that the presser foot may be adjusted vertically and laterally by means of the bolt and slots and may be held in position of adjustment by tightening the nut 1071 The horizontal section of the presser -foot to the rear of the vertical arm 103 is provided with an upturned end 108 beneath which the piece of stool: passes, so that should such piece of stock he slightly tilted upward, or have the tendency to move up- Ward, it will be depressed and properlyA guided beneath the main portion of the presser foot. .The forward horizontal section 109 of the presserfoot extends to a point approximately in line with the center of the saws so that the pressing action of the /lioot is maintained until the stock is brought iiwellf' within cutting positionv at the saws` Th iT-air'tuble C, as will be seen by refer-I ing in the kerf, or cut tendl to Separate the two pieces of the stock so that the latter will not bind or pinch on the rotating saws and interfere with the operation of the latter. It will further be seen that these spreaders may be adjusted vertically and laterally to correspond to the adjustment of the saws, and will be moved bodily when the tilting frame is swung on the main casting, asbeibre described, so that the proper alinement of spreaders relative to the saws will be maintained in the cutting of the bevel stock. Referring to Figs. 1, 2 and, it will be seen that each saw is partially incas/ed by a' cover 161, the vertical wall l162 of which is cut away as at 163 to permit the dust tube 137 to extend therethrough. This cover is bolted to the machine as at 164, and it is seen that it forms a dust chamber from which the saw dust is drawn through the tube 137, so

that the saws may be kept comparativelyn clear of waste.

Referring especially to Figs. 3 and 5 of the drawings, it will be seen that the two circular saws are so arranged that they describe intersecting circles in their Arotation, that is the teeth s of one saw in rotation will pass through the kerf s of the opposite saw, but without, of course touching or contacting. By so arranging the saws the cutting edges overlap, with the resultthat a clean kerf is made through the piece of stock and is free from ridges or other irregularities. For the purpose of sharpening the circular saws while running, I make use of the device shown in Figs. 2O and 21 of the drawings, itbeing, of course, understood that I use one of these sharpening devices for each saw. This de-A vice which is indicated as an entirety by the Alettter G, comprises a standard 165, which is mounted on the ear 166 of the plate 134. This standard is provided with a sliding block 167 through which passes the adjusting screw shank 168, which also extends at its upper end through the collar 169 carried by thestandard 165. A handle 170 yis provided for rotating the` shaft 168 and the latter is held against vertical movement b`y means of the nut 171. Thus by the rota-V tion of the crank handle 170 the block 167 will be fed up and down the sleeve. This block carries a holder 172, having an open face 173, through which is exposed: a piece of emery stone 174, orother suitable sharpening material. The holder maybe of any suitable construction and is preferably so .formed that the `emery'may readily be inserted and removed. The block 167 carries an arm 175 throughwhichkextendsthe .1

shank of the set screw 176, the vend of the shank being designed to Abear against -the adjacent wall of the machine when the'.` Sharpener is in operative position, as shown` inFigs. 20 and 21. 'As tho 0011er '169l 'and the block 167 may'turn on'the standard 165,

the sharpening device 'may be.=readily swung out of the wayv lof.' the saws after the latter have been sharpened s'uicie'ntly. The

sharpening edge 177 of theemery is prop.

erly beveled Aand adjusted relative `to the' saw teeth so that Aas' will befseenby'reference to Figf'21 the .teeth of the saws, 'as the latter rotate, are lightly touched 'or tip. ed

"1.51 by the beveled edge of the emery, and 't are kept constantly sharpened. Itzmaybe necessary at intervals in the operation to true up the circular saws, as the teethlaleA liable to be slightly bent or vSprung outfof alinement Vunder constant work, andv tol speedily and accurately accomplish such truing, I provide the attachmentwhich isl w indicated as an entirety by the letteiiH. In this attachment ther numeral 1781'indi- Cates a block which is designedto be attached to and extend between the endsgof the arm section 110, and this block it is to be understood, may be slipped on and olf thel ends of the arms.y The block is bored verti,

cally as at 179 and through this' bore extends the vertical stem 180,'which is threaded at its free end at 181 forthe reception of the adjusting thumb nut 182 and the locking nut 183. This adjustingnut 182 is fianged at 184 and is rotatably mounted relative to the block by the ring 185. The

bear against the bottom faces of xthe saws..

Thus as the saw teeth are carried past these blocks they tip against or contact with the latter and are forced to their true ositions. It is to be understood thatthese blbcks 189 are used merely for the purpose oftruing .or side dressing the saws when preparin for the sawingbperation, and are remove l. when such sawmg operatlon is in pro ess,

In order that the main casting or ame may be capable of adjustment relative to the bed plate in assembling the machine, so that it may be brought intovproper alinement with the planer, I use tubular adjusting bolts 190 threaded through the bores ,191 in iop the lugs 192at the base of the main ,f
